Professor Jean-Pierre Finance, Chair of the EUA Science2.0/Open Science Expert Group, will explain EUA approach towards Open Science by bringing together first-hand information and experience from three main areas: 1) Open Access policies (universities through EUA’s survey on Open Science - data from 500 universities; research councils – through Plan S); 2) financial aspects, through its survey on "Big Deals" (data from 31 National Consortia) and Publish&Read Project; 3) research assessment for research careers (briefing). EUA implements its Roadmaps on Open Access (2016) and on Research Assessment (2018) in close collaboration with its ad-hoc groups: Expert Group on Science 2.0/Open Science, the High-Level Group on Big Deals and the Negotiators Group. EUA develops strategic positions, surveys and workshops which are becoming a reference for universities and in the framework of the EC Open Science Policy Platform (OSPP).
